All I can tell you is what I see on the COE Green River Facebook page from this morning :
"Lake Level Update: as of 6:00 am lake level is 673.72 msl with a setting of 3 tenths on the main service gates for an outflow of around 1,302cfs (cubic feet of water per second). Surface Temperature: 55° F " (note: this temp reading is taken at the dam)
Versus what I had been seeing, which was a lake level rise from 670 to 673 with an outflow of only around 50cfs over the past 3-4days ... which tells me the Green River (below the dam) has receded enough for them to crank up the outflow and start pulling the lake back down.
Maybe t.slabseeker will chime in with more details.
